Without Arrow to pave the way, there would have been no Flash, and we possibly would have missed the whole universe of characters that we see on The CW.

Grant Gustin made his first appearances as Barry Allen during Arrow’s second season, and he made a post on Instagram applauding Arrow for leading the way as it goes into its final season.

“It kinda just hit me this morning that Arrow will be leaving us next year,” Gustin wrote. “Ever since I started doing this, it’s always been “Flash & Arrow” (or really this should of said “Arrow & Flash” on it’s cover….right, Stephen?)We don’t get to see a lot of each other, because we both work very similar schedules, on different shows, for 9 1/2 months out of the year. But when we’re brought together for those grueling crossover episodes, it always results in something pretty special. And not JUST a special kind of hell. It’s just absolutely bananas to stand around with that many people in super suits, and get paid to play make believe on tv.”

“It’s something that wouldn’t happen year after year if it weren’t for the groundwork that Arrow, Stephen and the whole cast and crew laid for us,” Grant continued. “Not just that, but Stephen has always brought a different kind of passion to his show and the whole Arrowverse. It’s always been clear to me how much it means to Stephen to have the privilege of getting to go on this journey as Oliver Queen. And how much care he’s always put towards it. I will never forget ohh soo many memories we shared together during our hundreds, if not thousands of hours of crossover filming. Thank you to everyone who was a part of making Arrow for letting me come on this journey with you all. Congratulations on a badass show that will live on forever. I’ll never forget binge watching season one and being scared shitless my first day on set, seeing you all in person. Stephen, you’re a legend. Maybe this means we can hang out more?”
